Title:ResearchandDesignofMEMSCapacitiveAccelerometerContinuousClosed-LoopReadoutCircuit

Introduction:

Accelerometersareoneofthemostimportantsensorsusedinvariousfieldssuchasaerospace,automotive,biomedicalandstructuralengineering.MEMScapacitiveaccelerometershavegainedsignificantattentionduetotheirsmallsize,lowcost,andhighaccuracy.However,toachievehigh-performancemeasurements,ahigh-performanceclosed-loopreadoutcircuitisrequired.Therefore,thisprojectaimstoresearchanddesignaMEMScapacitiveaccelerometercontinuousclosed-loopreadoutcircuit.

Objectives:

Themainobjectivesofthisprojectare:

1.TostudytheworkingprincipleofMEMScapacitiveaccelerometersandtheircontinuousclosed-loopreadoutcircuit.

2.Toevaluatetheperformanceofdifferentreadoutcircuittopologiesandchoosethebest-suitedtopology.

3.TodesignandsimulatethechosentopologyusingsoftwaretoolssuchasCadenceVirtuosoandMATLAB.

4.ToimplementandtestthedesignedcircuitonaPCBandvalidateitsperformancethroughexperimentalmeasurements.
